A Comprehensive Guide to Claiming Cybersecurity R&D Tax Credits for Eligible Projects

Published by Sidra posted in Research And Development (R&D) on November 5, 2025

Businesses operating in the cybersecurity industry face increasingly complex threats. Staying ahead of cybercriminals requires continuous innovation in technologies like encryption, threat detection, and AI-driven security. The good news is that if your business is developing new solutions to combat these threats, you may qualify for Research & Development (R&D) tax credits. However, many businesses fail to realise that their work can qualify for financial relief, resulting in missing out on significant opportunities to reinvest in their operations. At Apex Accountants, we specialise in claiming R&D tax credits for cybersecurity, maximising your potential for tax rebates or cash payments.

Why Cybersecurity Innovation Qualifies for R&D Tax Credits

Cybersecurity is an area of continuous innovation. Businesses must adapt rapidly to evolving threats and constantly experiment with new technologies and techniques. HMRC’s R&D tax relief is designed to support companies that push the boundaries of science and technology, making cybersecurity a prime candidate for tax credits.

To qualify for R&D tax relief, your project must meet certain criteria:

  • Innovation: Your work must introduce new methods, technologies, or solutions that haven’t been done before.
  • Scientific or Technological Uncertainty: There must be an element of uncertainty about how to achieve the solution or resolve a problem, making experimentation and trial-and-error a necessary part of the process.
  • Systematic Investigation: The project must involve a process of systematic investigation, testing, and development to resolve technological challenges.

Cybersecurity projects that address technological challenges in encryption, AI security, data protection, and other areas often meet these criteria.

Which Cybersecurity Projects Qualify for R&D Tax Relief?

Cybersecurity projects that focus on solving technological challenges, creating new solutions, or improving existing ones may qualify for R&D tax credits. Here are some specific areas where companies can claim cybersecurity tax credit:

Cryptography & Encryption

  • Post-Quantum Cryptography (PQC): Developing encryption methods that can withstand quantum computing threats qualifies as an indirect R&D activity.
  • Homomorphic Encryption: Creating encryption techniques to protect sensitive data during processing and testing is eligible for R&D tax credits.
  • Key Management: Managing cryptographic keys securely during research activities counts as R&D if it helps safeguard systems.

AI & Threat Detection

  • Intrusion Detection Systems (IDS): Developing AI-based systems that use machine learning to detect and block cyberattacks is considered R&D.
  • Anomaly Detection Models: Building models to identify unusual patterns in data, which can indicate a potential breach, qualifies for tax relief.
  • Endpoint Detection and Response (EDR): Developing systems to detect threats and respond to attacks on endpoint devices like laptops and mobile phones.

Identity & Access Management (IAM)

  • Biometric Authentication: R&D tax credits can be claimed if you are developing or improving biometric systems, such as fingerprint or facial recognition for secure access.
  • Zero Trust Architecture: Implementing zero-trust models that enforce strict identity verification for every user and device can be eligible for R&D relief.

Cloud & Edge Security

  • Hybrid Cloud Security: Securing hybrid cloud systems involves solving challenges in interoperability and data protection, which qualifies as R&D.
  • Edge Device Security: Developing systems to secure Internet of Things (IoT) devices at the network edge is eligible for R&D tax relief.

Blockchain & Secure Audit Trails

  • Blockchain-Based Incident Reporting: Creating secure, verifiable incident reporting systems using blockchain technology qualifies for R&D.
  • Immutable Logging Systems: Designing tamper-proof audit logs to ensure data integrity in cybersecurity systems is R&D.

Privacy & Data Protection

  • Differential Privacy: Developing methods to protect sensitive information during analysis qualifies as R&D.
  • GDPR-Compliant Anonymisation: Building new techniques for anonymising data in compliance with GDPR standards can be claimed for R&D tax credits.

What Doesn’t Qualify for R&D Tax Relief?

While many cybersecurity projects are eligible for R&D tax relief, not every activity qualifies. Here are some examples of work that typically does not meet the criteria for the cybersecurity tax credit for R&D:

  • Routine Penetration Testing: This is a standard security practice, not considered a technological advancement.
  • General IT Maintenance: Routine updates or configuration of off-the-shelf software do not qualify for R&D tax relief.
  • Compliance Frameworks: Meeting standards like ISO 27001 or Cyber Essentials is important but does not count as R&D.

What Evidence Do You Need for Your Cybersecurity R&D Tax Credits Claim?

Proper documentation is crucial when making an R&D tax claim. To support your claim, you should keep records of:

  • Development Documentation: Keep records of experiments, code repositories, and testing logs.
  • Technical Uncertainty: Document the technological challenges you faced and how you overcame them.
  • Failure Reports: If experiments or prototypes didn’t work as planned, keep records to show your process of iteration and problem-solving.

These records help demonstrate to HMRC that your project meets the requirements for R&D tax relief.
